I've got a new server running Windows 2003 R2 x64 SP1. With an install
of Exchange 2007. All was going well migrating mailboxes, from a
Windows 2003/Exchange 2003 server, which is retiring. Then an
installation of SQL (I know they shouldn't be on the same box) pretty
much hosed the 64-bit portions of IIS.

I think I have all the IIS functions back to normal. The only errors
I am receiving now are these two.

The short version of the error that shows in IE is:

Outlook Web Access did not initialize. An event has been logged so
that the system administrator can resolve the issue. Please contact
technical support for your organization.

contacted via RPC interface, error 0x5.

Any help at all would be much appreciated. It appears that there are
not too many Exchange 07's in play now because postings appear to be
minimal.
